About the Cap Sauers Trail Marathon
The Cap Sauers Trail Marathon is held each May at Teason's Woods in the Cap Sauers Holding Nature Preserve near Palos Hills, Illinois, southwest of Chicago. The marathon covers two loops of the 10-mile course on the Sag Valley Trail system, then a 10K out-and-back to the Will-Cook Road aid station. The trails are wide horse trails with little technical running, and the race lists about 1,050 feet of elevation. A 10 Mile race runs the same loop, and the preserve is described as the largest tract of undeveloped land in Cook County.
